If you are actively engaged in P2P and are afraid of slowing down internet access for other users

within your network, you can then use QoS to set a rule that has low priority. In this way, P2P

application will not congest the data transmission with other applications.

Other applications, like FTP, Mail access, users can use QoS to control based on need.

QoS Port Shaping

QoS port shaping supports traffic shaping of Ethernet interfaces. It forcefully maximizes the throughput

of the Ethernet interface. When “Shaping Rate” is set to “-1”, no shaping will be in place and the “Burst

Size” is to be ignored.

Interface

: P1-P4. P4 used as EWAN also covered.

Type

: All LAN when P4 is LAN port; P4 used as EWAN, type WAN and all others LAN.

QoS Shaping Rate (Kbps):

Set the forcefully maximum rate.

Burst Size (Bytes):

Set the forcefully Burst Size.

NAT

NAT (Network Address Translation) feature translates a private IP to a public IP, allowing multiple

users to access the Internet through a single IP account, sharing the single IP address. It is a natural

firewall for the private network.

Exceptional Rule

Exceptional

Rule

is

dedicated

to

giving

or

blocking

NAT/DMZ

access

to

some

specific

IP

or

IPs(range).

Default Action

: Select “Allow” to grant access to the listed IP or IPs to Virtual Server and DMZ Host.

While choose “Block” to ban the listed IP or IPs to access the Virtual Server and DMZ Host.

Apply: Press Apply button to apply the change.

Exceptional Rule Range

Valid

: Check the box to enable or disable the IP range.

IP Address Range:

Specify the IP address range; IPv4 address range can be supported. Click Add to

add the IP Range.

For instance, if user wants block IP range of 172.16.1.102-172.16.1.106 from accessing your set

virtual server and DMZ host, you can add this IP range and valid it.

Virtual Servers

In TCP/IP and UDP networks a port is a 16-bit number used to identify which application program

(usually a server) incoming connections should be delivered to. Some ports have numbers that are

pre-assigned to them by the IANA (the Internet Assigned Numbers Authority), and these are referred

to as “well-known ports”. Servers follow the well-known port assignments so clients can locate them.

If you wish to run a server on your network that can be accessed from the WAN (i.e. from other

machines on the Internet that are outside your local network), or any application that can accept

incoming connections (e.g. Peer-to-peer/P2P software such as instant messaging applications and

P2P file-sharing applications) and are using NAT (Network Address Translation), then you will usually

need to configure your router to forward these incoming connection attempts using specific ports to the

PC on your network running the application. You will also need to use port forwarding if you want to

host an online game server.

The reason for this is that when using NAT, your publicly accessible IP address will be used by and

point to your router, which then needs to deliver all traffic to the private IP addresses used by your

PCs. Please see the WAN configuration section of this manual for more information on NAT.

The device can be configured as a virtual server so that remote users accessing services such as Web

or FTP services via the public (WAN) IP address can be automatically redirected to local servers in the

LAN network. Depending on the requested service (TCP/UDP port number), the device redirects the

external service request to the appropriate server within the LAN network.

This part is only available when NAT is enabled.

Note:

The maximum number of entries: 64.

It is virtual server listing table as you see, Click Add to move on.

The following configuration page will appear to let you configure.

Interface:

select from the drop-down menu the interface you want the virtual server(s) to apply.

Server Name:

select the server name from the drop-down menu.

Custom Service:

It is a kind of service to let users customize the service they want. Enter the user-

defined service name here. It is a parameter only available when users select Custom Service in the

above parameter.

Server IP Address

: Enter your server IP Address here. User can select from the list box for quick

setup.

External Port

i

Start: Enter a port number as the external starting number for the range you want to give

access to internal network.

i

End: Enter a port number as the external ending number for the range you want to give

access to internal network.

Internal Port

i

Start: Enter a port number as the internal staring number.

i

End: Here it will generate automatically according to the End port number of External port

and can’t be modified.

Protocol:

select the protocol this service used: TCP/UDP, TCP, UDP.

Time Schedule:

Select or set exactly when the Virtual Server works. When set to “Always On”, the

Virtual Server will work all time; and also you can set the precise time when Virtual Server works, like

01:00-19:00 from Monday to Friday. Or you can select the already set timeslot in

Time Schedule

during which the Virtual Server works. And when set to “Disable”, the rule is disabled and there will be

an icon

in the list table indicating the rule is disabled. See Time Schedule.

Set up

Select a Server Name from the drop-down menu, then the port will automatically appear, modify some

as you like, or you can just leave it as default. Remember to enter your server IP Address.
